Auto login is not working in Safari browser(Version 8.0.3 (10600.3.18)) on OS X (Yosemite 10.10.2)

ie., it doesn't detect and show 'Welcome back, < user >. You've been logged in. Click here to refresh the page.'

JS and Cookies are enabled. There are no errors in the console as well.

Situation: I am logged in on meta.stackexchange.com, but it doesn't show that I am logged in when I visit stackoverflow.com & other stack exchange sites

    There are a LOT of weirdness in how cookies work in Safari when you navigate across our 2nd-level domains (from SO to SF, say.) There are some improvements in the works that will solve some, but not all of em.

My impression is that's caused by the way stackauth.com authentication was implemented, which breaks with new anti-tracking security settings of the browsers, especially Safari 9 on Mac OS X.

If you enable: allow cookies from all domains, it seems to be working.

See my own ticket: Why do Stack Exchange sites seem to always forget my login?
